What is Slippery Willy?
1.
while having sex with a girl doggie style and then right befoe you are about to come you will make her kneal on her knees with her head touching the floor. Then you will cum all over her back and rub it around. Then slide down on it like a water slide. This act normally involves a small boy and a big fat girl inorder for it to work quite properlly
